Clearnet version is online at
whirlwind.money. Please keep in mind that we are not using cloudflare/ddos guard and never will since we believe it's inappropriate for a platform of this type (regardless if we assume the end-user takes proper security precautions), so the clearnet link may be down at times. We implemented a custom protection, but there is only so much you can do without a CDN. If the clearnet link is unavailable please use the Tor version, there shouldn't be any issues with that at any point unless we announce maintenance beforehand.
I checked your website with onion site. You have two options to select the deposit type: Fast and Note.
With Fast option, there is a Receiver's BTC address. Why not implement it similarly as with Note. May you explain about it, differences between Fast and Note options and why only with Fast option, there is an entry box for Receiver's BTC address. Can both use same method as Note?
With receiver's BTC address and user login data (I guess your platform will store that data before one mixing is completed and even after that), it can be a risk factor for user privacy.
With Fast mode you select all parameters (receiver BTC address, delay, % distribution for each receiver address) from the beginning, and once you send
BTC to our address the system will automatically distribute the
BTC according to your inputs without requiring any further action from your side.
With Note mode you only need to send
BTC to our address, and then at any point in time later you can go to "Withdraw Note", select all parameters (receiver
BTC address, delay, % distribution for each receiver address) and then the system will automatically distribute the
BTC according to your inputs.
We recommend using Note mode because it's more versatile and it helps strenghten the privacy set for the whole mixer. Our competitors only offer a fixed maximum delay (<200 hours) from the moment you deposited to the outgoing transaction, and that makes it easier to track addresses using blockchain analysis. Also with our competitors as far as I am aware it's not possible to have outputs bigger than inputs, which again makes it easier to track things. We don't have these limitations thanks to the Note mode, there is no "expiration date" and you can combine 2 or more Notes to add up their balances together (for example you can deposit 0.1
BTC from an address, 0.1
BTC from another address, combine the notes, and then withdraw 0.2
BTC to a new address.) With these additions from blockchain analysis perspective any outgoing transaction from Whirlwind could have originated from
any deposit to Whirlwind, so the privacy will only become stronger as time goes on.
I love the simplicity of the website. I would like if there was more information in the FAQ like is there a minimum deposit amount? What’s the log policy? I will be checking for future updates and I hope this mixer can build a good reputation in this bitcoin community.
Minimum deposit is 0.001
BTCFor Fast mode we keep logs for the first 24 hours (while the deposit address is active), after those hours pass everything is deleted. Even if your outgoing transaction exceeds the 24 hour period, we only know where to send the
BTC, but not where they came from.
For Note mode we only keep the public key and the amount, nothing about where the deposit originates from or where the balance gets sent to.
There is no way for me to prove what I just said about logs, and neither can any other competitor, so that's why we came up with a solution to this problem. The only issue with it is that it requires some help from the community, I am willing to take steps in that direction as soon as it becomes possible to do so. Please see this discussion for more technical info -
https://bitcointalksearch.org/topic/ultimate-bitcoin-privacy-discussion-5444933Unlike other mixers that makes delay optional for users as a result of protecting their identity and granting them privacy which varies based on the delay or time option you choose to get your bitcoin after mixing and the delay mixing time goes with certain percentage of fee payment having it in mind that the more the time delay in mixing, the more your privacy is guaranteed. Just as I have said, is it still applicable to your mixer as it is above?
For Fast mode there is a 200 hour delay limit, if you use Note mode there are no limits of any sort, you have full control over the process.
The mentions multi sig system, is it already implemented? I think it's not yet, in the case it's giving a false information.
Nice Ann design.
We are in the trust business, if we'd lie about something like this then we have no place doing what we do. You can read more about the multi-sig setup in the other thread I started.
